For book lovers reading this, chances are you already know what Goodreads is. If not, it’s basically a social network for readers. According to their website, it’s the largest of its kind in the world, with in excess of 3 million members.

The website allows you to become friends with people, recommend books, get recommendations, see reviews and scores and add books to your ‘shelves.’ Your virtual shelves are read, currently reading and to-read. It’s free to join, and the iPhone/iPod Touch App is also free to download and use. Feel free to discuss this review of Goodreads in our forums.
